ha ha funny enough I did what I knew I shouldn't do but for some reason I did it anyways. I took the largest flat head screwdriver that would fit in the breech and tried to unscrew the nipple from the breech plug and sure enough out came the breech plug with it!! I wasn't even crankin' on it yet!! Very dirty but not too bad, and now with a look down the barrel I saw what I feared... surface rust and maybe some mild pitting. How bad is it to shoot it without polishing the rust out? Will it just crash the accuracy??
After calling every gunsmith or firearms dealer in 100 miles I come to find that no one in southern wisconsin has a breech plug wrench for this thing...I think I might make one out of a long 3/8 socket extension...the female end on the socket is about .677" and the bolt of the gun is .703". I will just cut a slot in the female end of the extension as wide as the male portion of the breech plug and presto we have a custom wrench with no shipping and handling!! I will turn it with a 3/8ths wrench. Sound crazy enough to work??
